I've printed it on an Ender 3 with 0.1 layer and by mistake without supports. I would suggest, you better should use some supports.
I've made a gap in the silver parts to glue a wire inside, to give it more stability.
I've added a baseplate, to give it more thickness all together and changed the silver_part01. So it besser fits on the black part. Better use silver_part01_v2.stl
